Technical Field

The embodiments of the present application relate to the field of communications, and more particularly, to a method and apparatus for transmitting information.

Background

In a Long Term Evolution (LTE) -based Licensed-Assisted Access (LAA-LTE) system, a carrier on a Licensed spectrum is used as a main carrier, and a carrier on an unlicensed spectrum is used as an auxiliary carrier to provide services for a terminal device, wherein on the unlicensed spectrum, a communication device follows a principle of Listen Before Talk (LBT), that is, Before the communication device performs signal transmission on a channel of the unlicensed spectrum, the communication device needs to perform channel detection first, and only when a channel detection result is that the channel is idle, the communication device can perform signal transmission; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals.

When a New Radio (NR) technique is applied to an unlicensed carrier, a beamforming (beamforming) technique is introduced to improve spatial multiplexing transmission capability of a cell, and in this case, how to perform channel detection for data transmission is a problem worthy of research.

The method for transmitting information according to the embodiment of the present application is described below with reference to fig. 1 to 5, and it should be understood that fig. 1 to 5 are schematic flow charts of the method for transmitting information according to the embodiment of the present application, and show detailed communication steps or operations of the method, but the steps or operations are only examples, and other operations or variations of various operations in fig. 1 to 5 may also be performed according to the embodiment of the present application.

Moreover, the various steps in fig. 1-5 may be performed in a different order than presented in fig. 1-5, respectively, and it is possible that not all of the operations in fig. 1-5 are performed.

Fig. 1 is a schematic flow chart of a method 100 of transmitting information according to an embodiment of the present application, and as shown in fig. 1, the method 100 may include the following:

s110, a first device performs channel detection on a first channel on an unlicensed carrier using a first beam and a first energy detection threshold to determine whether a first time domain resource used by the first device for transmitting first information is available;

s120, in a case that the first time domain resource is available, the first device sends the first information through the first time domain resource.

Optionally, the first device may be a network device or a terminal device, and thus, the embodiment of the present application may be applied to a channel access process of a network device or a terminal device on an unlicensed spectrum.

In this embodiment, the channel access procedure of the network device or the terminal device may include: whether the channel is available is determined by detecting whether the channel is in an idle state.

For example, the network device and/or the terminal device may detect whether a frequency domain resource with a certain bandwidth (e.g., 20MHz) is currently in an idle state, or whether the frequency domain resource is used by other devices.

If the frequency domain resource is in an idle state, or the frequency domain resource is not used by other devices (i.e., the channel is idle), the network device and/or the terminal device may use the frequency domain resource to perform communication, for example, perform uplink transmission or downlink transmission.

If the frequency domain resource is not in an idle state, or the frequency domain resource is already used by other devices (i.e., the channel is occupied), the network device and/or the terminal device cannot use the frequency domain resource.

In particular, the first device may perform channel detection on a first channel on the unlicensed carrier using a first beam and a first energy detection threshold, wherein the first energy detection threshold is an energy detection threshold corresponding to the first transmission power, optionally, the channel detection may refer to that the first device may collect signal energy on the first channel within a period of time, compare an energy value with the first energy detection threshold, and if the energy value is greater than or equal to the first energy detection threshold, the channel may be considered occupied, and it may be determined that the first time domain resources for transmitting the first information are not available, or if the signal energy value is less than the first energy detection threshold, the channel may be deemed idle, the first time domain resource may thus be determined to be available, and further, the first information may be transmitted on the first time domain resource.

Optionally, the size of the first energy detection threshold may be determined according to the size of the transmission power used by the first device for signal transmission, for example, if the transmission power is smaller, the corresponding energy detection threshold may be larger, and the transmission power is larger, and the corresponding energy detection threshold is smaller.

It should be understood that, in the embodiment of the present application, a beam (or called a receive beam) used for receiving a signal may be understood as a Spatial domain reception filter (Spatial domain reception filter) used for receiving a signal; accordingly, a beam used for transmitting a signal (or a transmission beam) may be understood as a Spatial domain transmission filter (Spatial domain transmission filter) used for transmitting a signal. For two signals transmitted using the same spatial domain transmit filter, the two signals may be said to be Quasi Co-Located (QCL) with respect to spatial receive parameters.

Optionally, in this embodiment of the present application, the first beam (i.e., one or more of the receiving beams) for channel detection and the second beam (i.e., one or more of the transmitting beams) for signal transmission may be the same beam, or may also be different beams, which is not limited in this embodiment of the present application. It should be understood that when a first beam used for channel detection is a different beam than a second beam used for signal transmission, the spatial domain coverage of the first beam at least partially overlaps the spatial domain coverage of the second beam.

Optionally, in this embodiment of the application, a direction corresponding to the first beam may be omni-directional, that is, the first device may perform omni-directional channel detection, and then may perform directional data transmission.

It should be understood that, in this embodiment of the present application, a beam may include precoding processing in a data domain, or may also include precoding processing in an analog domain, or may also include precoding processing in the data domain and the analog domain, which is not limited in this embodiment of the present application.

In an existing communication system, a situation that a transmit-receive beam (beam) is not completely matched may occur, for example, when performing channel detection, a communication device may use a reception precoding in a coarse direction, but when transmitting a signal, the communication device may use a transmission precoding in a fine direction to improve a beam gain (beamforming gain) of data transmission, and for example, when performing channel detection in an omni-directional reception manner, a communication device may use a mode with a beam gain to perform signal transmission, and the like, thereby possibly causing a situation that the transmit-receive beam (beam) is not completely matched.

Taking downlink transmission between the network device and the terminal device as an example, as shown in fig. 2, before providing service for the UE1, the gNB1 may perform channel detection on interference in the direction in which the UE1 is located by using the beam direction 1 based on an energy detection threshold corresponding to the transmission power P, and if the channel is found to be idle, the gNB1 may perform data transmission on the UE1 by using the transmission power P and the beam direction 2. If the beamforming gain in beam direction 2 is greater than the beamforming gain in beam direction 1, the data transmission range of gNB1 may exceed the channel detection range of gNB1, and the data transmission from gNB1 to UE1 may affect the communication link around UE1, for example, the communication link between gNB2 and UE 2.

Based on the above technical problem, optionally, as an embodiment, S120 may specifically include:

the first device transmits the first information through the first time domain resource by using a second transmission power, wherein the second transmission power is different from the first transmission power, and the first transmission power is used for determining the first energy detection threshold.

As can be seen from the above description, if the channel detection range is smaller than the data transmission range, interference of data transmission on other communication links may be caused, and since the data transmission range exceeds the channel detection range, there may be some resources on the channel that are unavailable, and therefore, data transmission on the resources may result in data transmission failure and affect reliability of data transmission.

It should be understood that, in this embodiment, a second beam used by the first device to transmit the first information using the second transmission power may be the same as or different from a first beam used for channel detection using an energy detection threshold corresponding to the first transmission power, and this is not limited in this embodiment as long as a channel detection range can be greater than or equal to a data transmission range by controlling a relationship between the second transmission power and the first transmission power.

It should be noted that, in the embodiment of the present application, the spatial domain coverage range corresponding to a beam may be jointly determined by the corresponding direction, the coverage angle, and the signal amplitude (i.e., the beam gain) of the beam. If the spatial domain coverage range corresponding to the first beam used for receiving the signal is completely the same as the spatial domain coverage range corresponding to the second beam used for transmitting the signal, the first beam and the second beam can be considered to be the same; otherwise, the first beam and the second beam may be considered different. The spatial coverage corresponding to the first beam and the spatial coverage corresponding to the second beam are completely the same, which may mean that the corresponding direction, the coverage angle, and the beam gain of the first beam are the same as the corresponding direction, the coverage angle, and the beam gain of the second beam. Optionally, if the coverage angle of a beam is smaller, the beam gain corresponding to the beam is larger; conversely, the larger the coverage angle of a beam is, the smaller the beam gain corresponding to the beam is.

Based on the technical problem shown in fig. 2, as another embodiment, S120 may specifically include:

the first device transmits the first information over the first time domain resource using a second beam, wherein the second beam is different from the first beam.

Here, the second beam and the first beam being different may mean that at least one of a coverage angle and a signal amplitude of the first beam and the second beam are different, and a corresponding direction of the first beam and a corresponding direction of the second beam at least partially overlap. The first device performs data transmission using a second beam different from a first beam for channel detection, so that the first device can control spatial coverage of the first and second beams (e.g., by controlling an energy detection threshold, signal transmission power, or selection of the first and second beams, etc.) so that the channel detection range at least covers a data transmission range, thereby avoiding interference of data transmission on other communication links.

It should be understood that, in this embodiment, the second transmission power used by the first device to transmit the first information may be equal to or different from the first transmission power corresponding to the energy detection threshold used by the first device to perform channel detection, which is not limited in this embodiment, that is, in this embodiment, the first device may control the spatial-domain coverage of the first beam and the spatial-domain coverage of the second beam to make the channel detection range greater than or equal to the data transmission range.

Optionally, the first beam may be a beam in a first beam set, and the second beam may be a beam in a second beam set, where the first beam set may be a set of beams used for channel detection (or signal reception), and the second beam set may be a set of beams used for signal transmission, and at least one beam in the first beam set and the second beam set is different. For example, the number of beams included in the first beam set and the second beam set is different, the first beam set includes N beams, N is a positive integer, the N beams correspond to different directions, the second beam set includes M beams, M is a positive integer, the M beams also correspond to different directions, and the N beams in the first beam set correspond to the same direction and coverage angle as the M beams in the second beam set. Assuming that M is 2 × N, the direction and coverage angle corresponding to one beam in the first set of beams is the same as the direction and coverage angle corresponding to the union of two beams in the second set of beams, in which case optionally the beam gain of one beam in the first set of beams is smaller than the beam gain of one beam in the second set of beams.

Optionally, in some embodiments, the first device may also combine the information of the beam and the transmission power, and control the channel detection range to at least cover the data transmission range.

For example, in the case that information (e.g., corresponding direction, coverage angle, signal amplitude or beam gain) of the first beam and the second beam is determined, the first device may control the size of the channel detection range and the data transmission range by controlling the size of the first transmission power and the second transmission power.

It should be understood that, in the embodiment of the present invention, data transmission may be transmission of a physical channel or transmission of a reference signal, where the physical channel includes an uplink physical channel or a downlink physical channel, and the reference signal includes an uplink reference signal or a downlink reference signal, which is not limited in this application.

Optionally, in this embodiment of the present application, the first device may determine the first transmit power, the second transmit power, the information of the first beam, and the information of the second beam by itself, for example, the first device may determine the first transmit power first, and then determine the second transmit power according to the first transmit power. Alternatively, the first device may also determine the second transmission power first, and then determine the first transmission power according to the second transmission power. Alternatively, the first device may also determine the first transmit power and the second transmit power simultaneously.

Optionally, in this embodiment of the present invention, for the first beam, the second beam, the first transmit power, and the second transmit power, the first device may determine the fourth parameter through any three parameters of the first beam, the second beam, the first transmit power, and the second transmit power, which is not limited in this application. For example, the first device may first determine the first beam, the second beam, and the first transmit power, and then determine the second transmit power for data transmission based on these three parameters. For another example, the first device may determine the first beam, the second beam, and the second transmission power, and then determine the first transmission power according to the three parameters, thereby determining the energy detection threshold corresponding to the first transmission power for channel detection.

Case 1: the corresponding direction and coverage angle of the first beam are greater than those of the second beam, and the signal amplitude of the first beam is smaller than that of the second beam, or the beam gain of the first beam is smaller than that of the second beam, for example, the scenario shown in fig. 2.

In this case, the first device may perform channel detection using the first beam and a first energy detection threshold corresponding to the first transmission power, and perform data transmission using a second transmission power after the channel detection is successful (i.e., the channel detection result is idle), where the second transmission power is smaller than the first transmission power.

Alternatively, the first device may control a difference between the first transmission power P1 and the second transmission power P2 to be greater than or equal to a certain adjustment amount X, so as to enable a data transmission range to fall within a channel detection range, that is, the channel detection range at least covers the data transmission range, wherein the adjustment amount X is determined according to a difference between a beam gain of the second beam and a beam gain of the first beam.

Alternatively, X may be a difference between a beam gain of the first beam and a beam gain of the second beam, for example, X may be a power difference between the beam gain of the first beam and the beam gain of the second beam, or X may be an energy difference between the beam gain of the first beam and the beam gain of the second beam, or X may be a signal-to-noise ratio difference between the beam gain of the first beam and the beam gain of the second beam.

Optionally, in this embodiment of the application, the beam gain of the first beam may also be understood as a first precoding gain obtained based on a first precoding corresponding to the first beam, and the beam gain of the second beam may also be understood as a second precoding gain obtained based on a second precoding corresponding to the second beam.

Accordingly, X may be a power difference between a first precoding gain and a second precoding gain, or X may be an energy difference between the first precoding gain and the second precoding gain, or X may be a signal-to-noise ratio difference between the first precoding gain and the second precoding gain.

For example, assuming that the first device plans to perform data transmission using the second beam and the second transmission power, and plans to perform channel detection using the first beam, where the direction and the coverage angle corresponding to the first beam include (or cover) the direction and the coverage angle corresponding to the second beam, the beam gain of the first beam is 3dB, the beam gain of the second beam is 6dB, and the second transmission power P2 is 17dBm, the first device determines that the difference X between the beam gain of the first beam and the beam gain of the second beam is 6dB-3dB, and accordingly, the first transmission power P1 should be greater than or equal to the sum of the second transmission power P2 and X, that is, P1 should be greater than or equal to 17+ 3-20 dBm, that is, that the first device should determine the first energy detection threshold according to the first transmission power not less than 20 dBm.

Therefore, in the case that the corresponding direction and the coverage angle of the first beam for channel detection are greater than those of the second beam for data transmission, if the beam gain of the first beam is smaller than that of the second beam, the first device may perform channel detection with a larger first transmission power, or may perform data transmission with a smaller second transmission power, so that the data transmission range is smaller than or equal to the channel detection range, and further, the problem of interference caused to other communication links due to mismatching of the transmission beam and the reception beam can be reduced.

Case 2: the corresponding direction and coverage angle of the first beam are greater than the corresponding direction and coverage angle of the second beam, and the signal amplitude of the first beam is greater than the signal amplitude of the second beam, or the beam gain of the first beam is greater than the beam gain of the second beam, for example, the scenario shown in fig. 3.

It should be understood that in this case the first beam may comprise a plurality of beams, e.g. the first beam comprises 3 beams and the second beam comprises 1 beam in fig. 3.

In this case, optionally, the first device may perform channel detection using the first beam and a first energy detection threshold corresponding to the first transmit power, and perform data transmission using a second transmit power after the channel detection is successful (i.e., the channel detection result is idle), where the second transmit power is equal to the first transmit power.

Optionally, the first device may perform channel detection using the first beam and a first energy detection threshold corresponding to the first transmission power, and perform data transmission using a second transmission power after the channel detection is successful (i.e., the channel detection result is idle), where the second transmission power is greater than the first transmission power.

Alternatively, the first device may control a difference between the second transmission power P2 and the first transmission power P1 to be less than or equal to a certain adjustment amount X, so as to enable a data transmission range to fall within a channel detection range, that is, the channel detection range at least covers the data transmission range, wherein the adjustment amount X is determined according to a difference between a beam gain of the first beam and a beam gain of the second beam.

For example, assuming that the first device plans to use the second beam and the second transmit power for data transmission, and plans to use the first beam for channel detection, wherein the first beam comprises 2 beams, the direction and the coverage angle associated with the two beams comprised by the first beam comprises (or covers) the direction and the coverage angle associated with the second beam, the beam gain of each of the 2 beams comprised by the first beam is 6dB, the beam gain of the second beam is 3dB, and the second transmit power P2 is 20dBm, then the first device determines that the difference X between the beam gain of the first beam and the beam gain of the second beam is 6dB-3dB, and accordingly, the first transmit power P1 should be greater than or equal to the difference between the second transmit power P2 and X, i.e., P1 should be greater than or equal to 20-3-17 dBm, i.e., the first device should determine the first energy detection threshold based on the first transmit power not less than 17 dBm.

Therefore, under the condition that the corresponding direction and the coverage angle of the first beam for channel detection are larger than those of the second beam for data transmission, if the beam gain of the first beam is larger than that of the second beam, the first device can perform channel detection through smaller first transmission power, or the first device can perform data transmission through larger second transmission power, so that the data transmission range is smaller than or equal to the channel detection range, the transmission power of the data transmission is improved under the condition that the interference caused by the mismatching of the transmission beam and the reception beam on other communication links can be reduced, and the reliability of the data transmission is ensured.
